Research On Logistics Park Common Delivery Vehicle Scheduling Optimization

It is very necessary to the logistics park planning and construction from the view of modern logistics system. Meanwhile it need further study of customer requirements, integrate of existing logistics resources to build logistics park joint distribution mode, and optimize of logistics park joint distribution vehicle scheduling, maximum limit raise the use efficiency of logistics park logistics resources, eliminate unnecessary logistics link, reduce the logistics cost of enterprises. in this way,it will improve the quality of logistics service and obtain the biggest economic benefit. therefore, the logistics park joint distribution vehicle scheduling optimization research has the very vital significance in this paper.First, the paper mainly analysis of the meaning of logistics park and the meaning of classification, and the meaning of distribution and development course, Meanwhile the paper elaborate the joint distribution which will bring benefits for the enterprise. at the same time, Japan carrying out joint distribution situation is introduced in detail from the enterprise to participate in the situation of the joint distribution, joint distribution of the contents, for the purpose of the joint distribution and joint distribution of effect etc. and it is very necessary for the construction of logistics park to plan the model of common deliverySecondly, the article mainly discusses the logistics park distribution situation, finds out the existing problems and puts forward the development direction of logistics park distribution modes., at same time, the paper compare the self-distribution model, third-party logistics and distribution patterns, and common-mode three classic models. Meanwhile, the paper constructs the logistics park distribution cost model, and selects the logistics park distribution mode based on the cost-volume-profit model, provides guidance and advice to the distribution pattern of logistics park planning and construction and enterprise.Finally, this paper analysis method to determine the joint distribution center logistics park distribution task priority, and build the distribution priority model based on system clustering method and the priority coefficient model. at the same time the paper analysis of all kinds of distribution produced in the process of the cost including: delivery delay in transport costs, distribution, or the punishment cost in advance and super mileage compensation costs, And build distribution cost function expression, puts forward relevant constraints, build logistics park vehicle scheduling optimization model based on the priority. At the same time, the paper put forward the thought of solving the model and algorithm. At last the validity of the phase of the model is verified by an example.
